The series (1+x)^n is valid if:
Correct answer: B. -1 ≤ x < 1
- A. x ≤ 1
- B. -1 ≤ x < 1
- C. x > 1
- D. x =1
Explanation
The binomial series (1+x)^n is defined and convergent when the value of x lies between -1 and 1, i.e., -1 ≤ x < 1.When x is greater than or equal to 1, the series diverges and is not valid.

About Sequences and Series
Sequences describe ordered terms formed by a pattern, while series represent the sum of those terms. Questions cover arithmetic and geometric sequences, their nth terms, common difference or ratio, finite sums, and applications, with the sequence itself kept distinct from the corresponding series.
